ELECTROPLATING-FRAM E.

SPECIFICATION forming part of Letters Patent No. 224,478, dated February 10, 1880.

Application filed May 12, 1879. I

To all whom it may concern:

Be it known that I, JULIUS W. ROGERS, of West Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Electroplating-Frames; and I do hereby declare the following, when taken in connect-ion with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a perspective view.

This invention relates to an improvementin what are called frames, used in electroplating-that is to say, the frame or device used to support articles in the bath while being coated, and in such work itis necessary to immerse the articles, while on the frame, in hot potash-water or some equivalent therefor;

hence any coating on the frame of asoft character, such as Wax, india-rubber, &c.,'will be destroyed by the heat or acids; and without a coating of some character the precious metal will be deposited on the frame equally with the articles it supports; and in the usual practice the frame is from time to time scraped to remove and save the precious metal. This is a laborious process, barely paying for the trouble.

The object of this invention is to protect the frame by such a coating that it will not which completes the frame ready for use.

This vitrified coating will not receive the metal in deposit; neither will it be aflected by heat or acids, and all loss of precious metal is avoided, and without any of the difficulties now experienced.

1 do not broadly claim coating frames for electroplating purposes, as such, I am aware, is notnew; but

What I do claim is-- An electroplating-frame having its surface coated with a vitrified material, substantially as and for the purpose described.

JULIUS W. ROGERS.
